If you don't include math.h and don't link with the math library you're free to define sin/cos/etc any way you like, aren't you? > Finally, for fabs, we should just be able to recognize the setcc/select > pair and generate that instruction. the C math library has abs and absf, so it's easier to recognize the function calls. Of course the previous comment also applies to this... - for now I've just implemented all of them as llvm.xxx intrinsics, but I'm a bit unsure how to lower these if the target does not support them and the program does not link with...

Hello, I'm currently adding the floating point math instructions (fabs, fsin, fcos ...) to the x86 instruction set. I'm a bit unsure how to make the back end actually generate these instructions, though. My current plan is to add llvm intrinsics for these instructions but I've noticed that llvm already handles C math library functions to some extent. It feels a bit strange to add
